NullPointerException when trying to use plugin to build an image. #16

Closed scmadmin closed 9 years ago

scmadmin commented 9 years ago

Added a build step to do a docker build. It throws a NPE.

Digging into the code, it looks like dockerClientConfig is null, and only gets set if the build is being done on a docker slave. I'm trying to do the build on jenkins master.

My setup is jenkins on docker, with the docker URL set back to the host. That part seems to work ok.

here is the code where dockerClientConfig does not get set.

Hi all, I'm really very sorry I didn't look on this issue sooner. This is different plugin (docker-build-step plugin not docker plugin). Please file the issue into Jenkins JIRA under Docker component (i.e. here). Thanks and sorry once again.
